1 Claim.' (Cl. 182-23) This invention relates to traps used in plumbing in combination with lavatories, sinks and other plumbing fixtures, and in particular a trap having a fitting with a nipple having a threaded end and a perforated sleeve or spider carried by a cap threaded on the end of the nipple and extended into the fitting to intercept the passage of water from the trap whereby grease, sediment, and other forms of foreign matter are caught by the sleeve or spider and may readily be removed.

The purpose of this invention is to provide means for readily cleaning traps of plumbing fixtures without taking the trap apart.

In the conventional type of trap, particularly of the Por S type it is necessary to remove the unions or coupling elements to remove the U- fitting forming the trap and in this operation it is necessary to provide means for taking care of Water contained in the trap. With this thought in mind this invention contemplates a trap having an arresting element injected into an outlet passage thereof wherein it is only necessary to remove the arresting element in order to clean the trap.

The object of this invention is, therefore, to provide a cleaner for traps of plumbing fixtures with which the average layman may clean the trap.

Another object of the invention is to provide a cleaning element for traps of plumbing fixtures that may be installed in fitting connections of traps without changing the general design or arrangement thereof.

A further object of the invention is to provide a readily removable cleaning element for traps of plumbing fixtures that is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a, plumbing trap having a connection with an extended nipple having a threaded end and an arresting element carried by a cap threaded on the end of the nipple and extended into an outlet passage of the trap.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure l is a vertical longitudinal section through a plumbing trap of the type positioned in a drain of a lavatory showing an arresting spider in a vertical position and carried by a cap threaded on a nipple on the end of the vertical outiiow pipe of the trap.

Figure 2 is a cross section through the outow 2 pipel taken on line 2-2 of Figure l also showing the arresting element.

Figure 3 is anelevational view similar to that shownY in Figure l illustrating a modification wherein the cleaning element is positioned in a horizontal section of pipe.

Figure 4 is a longitudinal section taken on line 4-4 of Figure 3 showing the cleaner or arresting element mounted in the horizontal section of `the pipe.

Figure 5 i sa vertical section illustrating the type of fitting shown in Figure 1 with a perforated sleeve in the upperl end of the outflow pipe and with other Darts broken away.

' Figure 6 is a cross section through the sleeve and cleaner shown in Figure 5 being taken on line 6-6 thereof.

Figure 7 is a detail illustrating the perforated sleeve type of cleaner.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved trap cleaner of this invention includes a spider I0 carried by a cap II by a stem I2 and, as illustrated in Figure 1 the cap II is threaded on the upper end of a nipple I3 on the end of an outflow pipe I4 and the pipe I4 is provided with an elbow I5 that is connected to a U- fitting I6 by a union I'I, and the tting I6 is connected to a nipple I8 in the drain opening I9 of a lavatory 20 by a union 2I.

In the design illustrated in Figure 1 the spider I 0 is provided with radially disposed arms 22 that extend outwardly from the hub of the spider and the hub is secured to the lower end of the stem I2 with the upper end of the stem formed with a reduced section 23 that is secured in an opening in a boss 24 by forming a rivet head 25 on the end of the reduced section of the stem.

The threaded cap I I is provided with iiat sides 2G and the inner surface is provided with threads is threaded on threads 28 o the threaded boss 33 on the end of the U-tting I The spider Ill may be replaced by a perforated sleeve 34, as illustrated in Figures 5 and 7, the sleeve 34 being carried by a cap 35, similar to the cap l l, and the cap 35 is threaded on the threads 28 of the outflow pipe Id with a sealing gasket 36 between the end of the nipple I3 and the inner surface of the cap 35. The cap 35 is also provided With flat sides 31 to facilitate holding the cap by a wrench when inserting and removing the strainer or cleaner.

In the design illustrated in Figures 3 and 4 the outow connection I4 is replaced by a horizon-` 38 that is provided with a l.

tally disposed tube nipple 39 which is attached to theend. of. the.

U-tting I5 by the union l1.

tube 33 is provided with a threaded boss '40 upon which the cap Il is threaded and, as shown in the .Y

drawings the spider IB is suspended from the cap by a stem l2 and the stern is secured in the'capyas illustrated in Figures 1 and 4.

It will be understood that in the design illustrated in Figures 3 and 4 the arresting or straining element may be removed and replaced by a perforated sleeve, similar to the sleeve 34 and having a threaded cap 35 on the end thereof.

With the parts arranged in this manner the element I0, or the perforated sleeve 34 are inserted in a discharge or outovv passage of a plumbing trap and grease, hairs, sediment, and other foreign matter passing through the trap and arrested by one of the cleaning elements is readily removed by removing the threaded cap l I or 35 and withdrawing the elements suspended thereby. The foreign matter is readily cleaned from the elements and the element is readily inserted in the pipe or tube.

As illustrated in the drawing the threaded cap by which the cleaning element is suspended is having an elbow for attaching the overflow pipe -by one of `said coupling members to the short arm ofthe U-bend with one end of the overflow pipe extended for a connection to a drain, said over- Aflow pipe also having a threaded neck on the opposite end aligned with the said drain connection, and a cap threaded on the said threaded neck and means carried by said cap and extending into said overflow pipe beyond the connection of the elbow to said overflow pipe for cleaning the said drainy connection.
